SHANGHAI - Shanghai Municipal Food and Drug Inspection Institute said Tuesday the frying oil used by the US fast-food giant Kentucky Fried Chicken (KFC) is safe in Shanghai.

On Tuesday, the workers with the institute conducted tests on the oil used by some KFC restaurants in Shanghai to deep-fry chips and chicken, in response to recent media reports that criticize KFC over its use of oil.

The test results showed that all main indexes of KFC's cooking oil meet national standards.
